在python解析HTML - LXML或BeautifulSoup？哪一个是对什么样的目的更好？ [英] Parsing HTML in python - lxml or BeautifulSoup? Which of these is better for what kinds of purposes?

问题描述

这是我可以做出来，在Python的两个主要HTML解析库是LXML和BeautifulSoup。我选择BeautifulSoup一个项目我的工作，但是我选择了它比找到的语法有点容易学习和了解其他没有特别的理由。但是我看到很多人似乎赞成LXML和我听说lxml的速度更快。

From what I can make out, the two main HTML parsing libraries in Python are lxml and BeautifulSoup. I've chosen BeautifulSoup for a project I'm working on, but I chose it for no particular reason other than finding the syntax a bit easier to learn and understand. But I see a lot of people seem to favour lxml and I've heard that lxml is faster.

所以我不知道是什么了另一种优势？什么时候我会想使用LXML我时会关闭使用BeautifulSoup更好？是否有任何其他图书馆值得考虑的？

So I'm wondering what are the advantages of one over the other? When would I want to use lxml and when would I be better off using BeautifulSoup? Are there any other libraries worth considering?

推荐答案

对于初学者来说，BeautifulSoup不再是积极维护和的笔者甚至建议替代如LXML。

For starters, BeautifulSoup is no longer actively maintained, and the author even recommends alternatives such as lxml.

Version 3.1.0 of Beautiful Soup does significantly worse on real-world HTML than version 3.0.8 does. The most common problems are handling tags incorrectly, "malformed start tag" errors, and "bad end tag" errors.
